A good friend gave me some garden phlox a few years ago.
Not sure of the cultivar, but it could be this one. The color is about the same. It grows nicely without being invasive. I have also acquired at least 3 other cultivars in my back yard that mysteriously appeared 5 years ago. One is white and the others are pink and white (light pink and dark pink).
They bloom for a long time and are great cut flowers.

I also have the Purple Volcano (label has it as 'Barthirtythree') and it's bloomed non-stop each summer for the last 3 years - even after a light frost or two. We had a really wet summer so some of the lower leaves had mildew but it didn't stop the blooms. I just pinch them back as soon as the blooms die, and then I get another round or more each summer. As an update, I've now expanded to other Volcano colors (Red, Ruby and White) and after all these years, they continue to perform really well, with lots of blooms. The butterflies love them too!
